Why is subtracting an expression similar to distributing a –1?

a. You increase each term inside the parentheses by –1 in order to subtract each term, since subtraction is the additive inverse.

b. You multiply each term inside the parentheses by –1 in order to add each term, since subtraction is the multiplicative inverse.

c. You multiply each term inside the parentheses by –1 in order to subtract each term, since subtraction is the multiplicative inverse.

d. You multiply each term inside the parentheses by –1 in order to subtract each term, since subtraction is the additive inverse.

Answer:

What variable are you trying to solve? Imma just guess you are trying to solve for x since its on the left side so...

2x+3=r+2

Subtract three from both sides

2x=r-1

Divide 2 from both sides

x=r-1/2 OR

x=1/2r+-1/2

Using the combination formula, it is found that 20 different arrangements of the display are possible.

The order in which the paintings are displayed is not important, hence, the combination formula is used to solve this question.

Combination formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this problem, 3 paintings are chosen from a set of 6, hence:

[tex]C_{6,3} = \frac{6!}{3!3!} = 20[/tex]

20 different arrangements of the display are possible.

Step-by-step explanation:

Y axis is F(x), the function of X axis

So, the shipping cost(Y) is a function of the weight (X)

Step-by-step explanation:

A = 1/2 × at

a = 5/3 meter

t = 1/2 meter

A = 1/2 × 5/3 × 1/2

A = (1 × 5 × 1)/(2 × 3 × 2)

A = 5/12 m²

Answer: C

Step-by-step explanation: using Δx/Δy we find that the slope is -59. Since the y intercept is -176 using the plug in -235 = -59(1) + b, C is the only one that can match that answer.

Answer:

26

Step-by-step explanation:

The number of students in Regan's class will be 26.

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Regan's class is preparing for a field trip. Her teacher purchased bottled water for the journey and asked Regan to stock a cooler with 2 bottles for every student who is going, 3 of the students didn't turn in permission slips and aren't going on the trip. So, Regan stocks the cooler with 46 bottles of water.

The number of students:-

46 / 2 = 23

23 + 3 = 26

Therefore, the number of students in Regan's class will be 26.

Answer: 280

Step-by-step explanation:

                                                  (-11 - 17) (2 - 12) = 280/1 = 280

Subtract: -11 - 17 = -28

Subtract: 2 - 12 = -10

Multiple: the result of step No. 1 * the result of step No. 2 = -28 * (-10) = 280

Answer:

$3.00

Step-by-step explanation:

$3.00 x .2 = 0.60. added to original

The original price of the yo-yo in a shop is $3.

The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

It is given that the price of a yo-yo in a shop increased by 20% and is now $3.60.

The original price will be calculated as let the original price is x dollars. Then from the question, the expression will be formed as below:-

1.20x = 3.60

x = 3.60 / 1.20

Divide 3.60 by 1.20 to get the value of x.

x = $3

It means that the 20 percent is equal to the amount of $0.6.

Therefore, the original price of the yo-yo in a shop is $3.

Answer:

slope = 35/2

y intercept is 0

Step-by-step explanation:

the y-intercept is 0 because you can see from the graph that it intersect with y-axis at (0,0)

Slope = rise /run

pick a point (8, 140)

rise = 140

run = 8

slope = 140/8 = 70/4 = 35/2
